Hmm, from the looks of it I think u have [url] and [/url] typed in there twice, so one pair of them is showing as text while the other actually linked to where u had that banner. Please go to profile --> and delete those extra [url] and [/url] Hope it helps! Otherwise, just post here again ^^;;; Btw, if I'm not wrong then you're supposed to type it as:
http://www.something.com
and not like [url=http://something.com][url]_________________Thanx to Joanne Kuang for the awesome avatar!

Its not that, okashira. Just now, I've tried experimenting using the url function. Apparantly this forum's url function doesn't support linking image. It only support linking words. like
testing
. I tried this link [URL=http://img430.imageshack.us/my.php?image=file07542kd.jpg]
[/URL] on other forum and it works. Thats my conclusion. Hope it helps.
